The work of a welder is one of the specialist professions that are becoming more and more popular and profitable nowadays, and the demand for specialists in this field is great. It is also worth mentioning that the salaries of an experienced welder reach up to PLN 5,000 in Poland, in other European countries they range from EUR 3,000 to 6,000 per month. And in the US, a professional can earn up to $ 25,000 per month, so maybe it's worth taking a closer look at this profession?
What is welding?
It is the most common method of joining metals by heating them and melting them at the point of joining. You can melt with or without a binder. The most common heat source is the welding arc. It is produced thanks to the current that is generated by a welding device - a welder. There are several types of welding:
- Gas welding - fusing the edges of joined metals by heating them with a flame of burning flammable gas (usually acetylene). This method can be used for all types of non-ferrous metals and steel.
- Arc welding with coated electrons - in this method, metals are melted in places where they are joined by means of an arc the electrical connection between the workpiece and the coated electrode. It uses alternating or direct current. There are several covers, such as: acid (A), rutile (R), basic (B), rutile-acid (RA), cellulose (C), rutile-cellulose (RC) and others.
- MAG (Metal Active Gas) method - the arc of the consumable electrode is used here (solid wire or flux-cored wire - binder) in the shield of active chemical gases or gas mixtures (argon, oxygen, carbon dioxide). It works best when welding high-alloy, low-alloy and unalloyed steels.
- MIG (Metal Insert Gas) method - using arc welding with a consumable electrode (solid wire) in the shield of inert gases such as argon, helium, and their mixtures. Used for non-ferrous metals.
- TIG method - a process involving arc welding with the use of a non-consumable electrode in an inert gas shield (argon, helium and their mixtures). Although it is an inefficient method, it gives high precision and quality of workmanship. It is used in joining high-alloy and low-alloy steels, as well as non-ferrous metals, which include: copper, aluminum, magnesium (including their alloys), and nickel.
How to become a welder?
Anyone who believes that the profession of welder is for him and is determined to start his career must meet several requirements. First of all, an adult with at least basic education can become a welder. In addition, a welder's book is needed - in order to receive it, you must complete special vocational courses. Such courses are offered by the KURSO company, which issues certificates in Polish and English - honored in Poland and abroad. In addition to the above-mentioned requirements, the future welder should have good eyesight and general physical fitness.
